摘要： There is provided mechanisms for OTA testing of an AAS of an EUT. A method is performed by a network node. The method includes obtaining definition of a test signal to be transmitted or received by the EUT in accordance with a time/frequency resource grid. The method includes applying first beamforming weights to first selected resource elements of the time/frequency resource grid that give first beam directions according to a first type of configuration for first OTA testing of the AAS. The method includes applying second beamforming weights to second selected resource elements of the time/frequency resource grid that give second beam directions according to a second type of configuration for second OTA testing of the AAS. The method includes initiating transmission or reception of the test signal over the AAS using the time/frequency resource grid.

摘要： There is provided mechanisms for generating a beam set. A method is performed by a radio transceiver device. The method comprises generating the beam set as combination of at least two beam pairs. Each beam pair is formed by two respective beams with orthogonal polarizations. The two beams have their pointing directions separated by a first angular separation delta1>0. Neighbouring beam pairs have their pointing directions separated by a second angular separation delta2>0. The first angular separation delta1 is a function of the second angular separation delta2.

摘要： A network node causes transmission of DCI that includes information for scheduling two or more TBs over two or more communication slots. The two or more TBs are associated with two or more HARQ process IDs. The information includes one or more of: a PUCCH resource indicator configured to indicate at least one resource for use for transmitting HARQ feedback related to the two or more TBs; a DAI configured to indicate a position of HARQ feedback related to the two or more TBs, in a HARQ codebook; a HARQ process ID indicator indicating two or more HARQ process IDs; and one or more NDIs configured to indicate whether at least one of the two or more TBs is a retransmission.

摘要： A method and network node for dual connectivity for a wireless device are disclosed. According to one aspect, a method in a network node is provided for use in a dual connectivity mode to communicate with wireless devices (WDs), according to a first radio access technology (RAT), and to communicate with WDs according to a second RAT is provided. The method includes scheduling uplink and downlink signals to be transmitted and received by a first set of WDs such that the first set of WDs are operable to: receive downlink signals and transmit uplink (UL) signals using the first RAT only in even Transmission Time Intervals (TTIs) of the first RAT; and transmit uplink signals using the second RAT only in in UL TTIs of the second RAT that do not collide with even TTIs of the first RAT.

摘要： Systems and methods for broadcast/multicast transmission in a distributed cell-free massive Multiple Input Multiple Output (MIMO) network are disclosed. In one embodiment, a method for broadcasting/multicasting data to User Equipments (UEs) comprises, at each Access Point (AP) of two or more APs, obtaining long-term Channel State Information (CSI) for a UE(s) and communicating the long-term CSI for the UE to a central processing system. The method further comprises, at the central processing system, receiving the long-term CSI for the UE from each AP, computing a precoding vector (w) for the UE(s) across the APs based on the long-term CSI, and communicating the precoding vector (w) to the APs. The method further comprises, at each AP, obtaining the precoding vector (w) from the central processing system, precoding data to be broadcast/multicast to the UE(s) based on the precoding vector (w), and broadcasting/multicasting the precoded data to the UE(s).

摘要： A method performed by a first network node includes determining one or more Local node Identifiers. The method includes transmitting the one or more Local node Identifiers to a second network node neighboring the first network node, each of the one or more Local node Identifiers including: an Inactive-Radio Network Temporary Identifier, I-RNTI, profile valid for the first network node and associated with a full I-RNTI; and/or an I-RNTI profile valid for the first network node and associated with a short I-RNTI. The method includes transmitting a radio resource control, RRC, release message with suspend configuration to a user equipment, to transition the user equipment to RRC Inactive, the RRC release message including a Local node Identifier for the first network node and a UE context identifier.

摘要： Systems and methods are disclosed herein relating to wireless device behavior after rejection of a resume request triggered by a Radio Access Network (RAN) based Notification Area Update (RNAU) or upon cell reselection during resume. In some embodiments, a method of operation of a wireless device comprises transmitting, to a RAN node, a Radio Resource Control (RRC) resume request triggered by an RNAU and receiving, from the RAN node, an RRC resume reject message comprising a wait timer value in response to the RRC resume request. The method further comprises starting a wait timer initialized with the wait timer value and sending the RNAU when the wait timer has expired. Corresponding embodiments of a wireless device are also disclosed. Embodiments of a wireless device and methods of operation thereof related to the behavior of the wireless device upon performing a cell reselection during resume are also disclosed.
